Sapphire Radeon HD 6990 4GB Dual GPU in Original Box - Tested in Great Condition

For sale is this AMD Radeon HD 6990 Dual-GPU beast from my collection. I rigorously tested this card in 3DMark and other benchmarks, and it passed with flying colours. The asking price of £350 is how I value this card, as these GPUs are now getting quite rare, especially in this condition and with original box.
